PREFACE

This manual serves to explain the use of the αlpha CON 200

controller/transmitter. This manual functions in two ways: first, as a step-

by-step guide to help you operate the meter; second, it serves as a handy

reference guide.

This manual is written to cover as many anticipated applications of the

αlpha CON 200 controller/transmitter as possible. If there are doubts in

the use of the αlpha CON 200 controller/transmitter, do not hesitate to

contact the nearest Eutech Instruments Authorized Distributor.

Eutech Instruments cannot accept any responsibility for damage or

malfunction to the controller/transmitter caused by improper use of the

instrument. Remember to fill in the guarantee card and mail it mail to your

Authorized Distributor or Eutech Instruments Pte Ltd.

1INTRODUCTION

Thank you for purchasing a CON 200 ⅛DIN Conductivity Controller. This

controller is part of a series of quality process controllers available from Eutech

Instruments. These sturdy, economical conductivity controllers are designed with

the features and reliability of a much more expensive instrument.

Your controller includes:

•Removable terminal blocks for easy connections;

•Two mounting brackets for easy panel mounting;

Some features of this controller are:

•Two set point, two SPDT relay operation

•Scrolling, 14-segment LED guides user easily through setup functions

•Reliable power supply from 85 to 260 V AC, 50/60 Hz or DC withstands

voltage fluctuations

•Push-button operation from the front panel

•Single-point calibration for each individual range

•Adjustable hysteresis band prevents rapid contact switching around set-point

•Selectable automatic or manual temperature compensation

•Two-level password protection

•Removable terminal strips for quick and easy connections

•Built-in memory backup retains setup even if power fails, and lets you

configure unit before installation

•Isolated 4-20 mA output for remote monitoring or hard copy recording

2SAFETY INFORMATION

The Eutech Controller/Transmitter shall be installed and operated only in the

manner specified in the Instruction manual. Only skilled, trained or authorized

person should carry out installation, setup and operation of the instrument.

Before powering up the unit, make sure that power source it is connected to, is as

specified in the top label. Failure to do so may result in a permanent damage to the

unit.

The unit has live and exposed parts inside. If it has to be opened, make sure that

the power to the unit is off and disconnected.

The unit is Fuse protected. In the event the fuse has to be replaced, use only those

as specified in the manual.

The degree of protection against electric shock will be achieved only by

observance of the corresponding installation rules.

3.3 Wiring

Caution: Ensure electrical mains are disconnected before proceeding.

1. Connect the power supply to the three-pin terminal block

•VAC live wire = 1

•VAC neutral wire = 2

•VAC protective ground wire = 20 OR 21

alpha CON 200 controller accepts voltages from 85 to 260 VAC, 50/60 Hz or DC.

2. Connect the Pt 100 leads to terminals 13 to 15 of the seven-pin terminal block.

Either wire can be connected to either terminal. Terminals 13 and 14 must be

shunted unless using a 3-wire RTD.

NOTE: CON 200 is factory set for Automatic temperature compensation. MTC can

be selected in Program P4.0.

3. Power on the controller. The display automatically shows the Conductivity

reading, the µS and ‘MEAS’ annunciators lights.

NOTE: In the event Pt 100 is not connected or the connection is broken in the ATC

mode, the display flashes ‘OR’ to alert you.

3.4 Panel-mounting the controller

The supplied mounting hardware allows surface mounting to all panels and

protective enclosures. Mounting cut-out size is 91 x 45 mm.

To attach the mounting to the controller:

1. Align the catch to the side of the controller, and insert threaded rods through

catch.

2. Screw the threaded-rod through the catch in a clock-wise direction. Tighten

until the catch holds the controller firmly against the back of the panel or

protective housing. Repeat on the other side.
